MPLS General Information

Multiprotocol Label Switching (MPLS) is an emerging Internet Engineering T ask Force (IETF) sta ndard that i s currentl y in draft fo rm. Its pr imary goal is to provi de a standardized solution that supersedes existing proprietary solutions for integrating label-swapping and forwarding with network layer routing. MPLS works in an environment where traditional network layer routing protocols (for example, OSPF and BGP) are used to maintain the routing topology and forwarding in formation base (FIB) for each router.
In connectionless networks (those using connectionless network layer protocols), as a packet travels from one hop to another, each router must determine where to forward the packet based on the individual packet header. This decision process can be broken down into two major tasks: classi fying a set of packets as part of a forwarding equivalence class (FEC) and mapping each FEC to a next hop.
By classifying a set of packets as part of an FEC, the router uses the same forwarding criteria for each packet. All packets that belong to a particular FEC and that trav el from a particular node follow the same path. This group of packets is called a “stream .” A packet stream is a group of packets that follows the same path to a destination. I n a con v ention al IP netw ork, each ro uter hop e xamines ea ch packet to determine its destination.
1-2
Using MPLS, the examination of the packet is done only once. The first router assigns a label that defines the specific packet stream. Each intervening router then forward s packets ba sed on the fixed-length labels. Labels reside in the label information base (LIB), which contains both inbound and outbound labels associated with inbound and outbound interfaces.
Looking up a label is faster than interpreting the destination of an individual packet and routing data based on that destination. By assigning labels to packets or packet streams, the transmission speed of your network increases.

Label Distribution Entity

The label dis tribution entity is essentially the implementation of the Label Distribution Protocol (LDP). LDP is the set of proc edures and mess ages by which
label-switching routers (LSRs) establish label-switched paths (LSPs) through a network. LDP establishes these paths by mapping network layer routing information directly to data link layer switched paths.
LDP associates a packet stream with a speci fi c LSP and assigns the LSP a specif ic label. The label infor mation is distributed betwe en the LSRs and LERs to maintain stream mapping information.

MPLS Label Management

The MPLS label management (MLM) entity communicates with LDP. It is responsible for:
Establishing the de fault VC
Responding to requests from LDP (for example, requests for a label and
establishing VC communications)

Forwarding

1-4
Communicating with the ATM driver to set up and tear down VCs
The forwarding entity encapsulates and decapsulates the data that it sends and receives over the MPLS interface.
Outbound data is delivered to the encapsulation process by the higher layers and delivered to the lower-level driver for transmission to the MPLS network.
Inbound data is received from the MPLS network by the lower-level driver and delivered to the decapsulation process, wher e it is stripped of layer 2 protocol headers. The decapsulation process then passes the inbound data to higher layers for further processi ng.

Label Switching Router

A label-switching router (LSR) is a router that contains all label-sw itching interfaces. The LSR controls MPLS forwarding in the MPLS network. An LSR performs table lookup on received packets and, based on the packet label, forwards the packet or packet stream to the specified outgoing inter f ace. The LSR swaps the labels of the packet headers before transmitting the packets to the MPLS network.
Note:
An ATM LSR currently consis ts of an ATM switc hing de vice that w orks with a UNIX UltraSPARC workstation running Solaris and LDP. For information about how to configure an ATM LSR, refer to the documentation provided with your switching device.

Label Edge Router

A label edge router (LER) is an LSR that resides between the IP and MPLS networks. This router performs two generalized functions:
It receives non-MPLS traffic, labels that traffic, and forwards it to another
label-switching interface.
1-6
It receives labeled MPLS traffic, strips the label from the packets, and
forwards the traffic over a non-MPLS interface.
Note:
This guide describes how to configure the LER. For information about how to start M PLS on the router, see Chapter 2, “Starting MPLS.” For information about how to customize the ATM router interface for MPLS, see Chapter 3, “Customizing the MPLS Configuration.”

Customizing LDP Parameters

LDP is a protocol governing the set of procedures and messages by which label-switching routers (LSRs) establish label-switched paths (LSPs) through a network. LDP establishes these paths by mapping network layer routing information directly to data link layer switched paths.
You can customize the default values for LDP parameters, as described in the following sections.

Disabling and Reenabling LDP

By default, you enable LDP w hen you add an LDP session to the interface. However, you can disable and reenable the LDP session at any time. Enable the session to allow MPLS LDP to operate over the interface. Disable the session to turn off MPLS LDP on the inte rface.
To disable or reena ble LDP, complete the following tasks:

Changing the Local IP Address

The local IP address identifies the local IP address that LDP uses to establish the TCP connection to the LSR.
The default address, 0.0.0.0, is useful only under specific circumstances (for example, whe n using circuitless IP) . In most cases, you must enter a valid IP address for this inte rface in dotted-decimal notati on. If you sta rted MPLS with the default IP address of 0.0.0.0, you can change the address.
Note:
Bay Networks recommends that you use the IP address that you used
when configuring the IP protocol on this interface.

Setting the Default VC Transmit SCR
The transmit sustainable cell rate (SCR) specifies the upper limit of the ATM connection conforming average rate on the transmitting side. The average rate equals the total number of cells transmitted, divided by the duration of the connection. The default value, 0, indicates that the transmit SCR is off.
Using the SCR, you can define the future cell flow of a VC in greater detail than by using only the peak cell rate.
The SCR maps directly to the minimum cell rate (MCR). The MCR defines the minimum amount of guaranteed bandwidth allowed for the default VC on the ATM line.
When setting the SCR, keep the following in mind:
305754-A Rev 00
To be useful, the SCR must not exceed the PCR.
If you know the average rate, set the SCR approximately 10 percent higher than this value.
VCs may fail to operate with SCR values lower than 128 cells/s.
Entering 0 for the SCR turns off this function.
After you determine the tr ansmis sion ra te of you r ATM device, set the sust ainabl e cell rate within the specified range.

Customizing LDP Static Route Parameters

A static route is a manually configured route that specifies the transmission path that a datagram mus t fol low, base d on the datagram’s des ti nat ion address. A static route specif ies a tran smission path t o another net work. You configure a static rout e when you want to restrict datagrams to paths that you specifically configure. MPLS can use static routes to distribute LDP information throughout the MPLS network.
If you intend to use IP sta tic route s ov er MPLS, you must defi ne the IP st atic route prefix and the route mask for LDP. Defining the route prefix and mask does not configure the static route. Instead, these parameters provide information to LDP about the static routes that you configure.
Note:
You can configure IP static routes before or after you configure MPLS. For information about static routes or how to configure them, see Configuring IP, ARP, RIP, and OSPF Services.
The following parameters define the use of static routes by M PLS.

Enabling and Disabling Static Routes

By default, static routes are disabled on the MPLS interface. Accept the default, Disable, if you do not want MPLS to use LDP static routes over the interface. Specify Enable for MPLS to use LDP static routes over the interface.
To enable and disable LDP static routes, complete the following tasks:

You access MPLS parameters from the Edit MPLS Connector wi ndo w, which acts as a control access point for all MPLS parameters. This window provides information specific to each individual MPLS interface.
For any given interface, the Edit MPLS Connector window provides two buttons:
•LDP
•MLM By clicking on one of these buttons, you can access and edit the parameters
associated with that specific MPLS interface.

Site Manager Parameters
Parameter: Xmt Sustainable Cell Rate
Path: Configuration Manager > Circuits > Edit Circuits > Edit > MPLS > LDP >
Default VC
Default: 0
Options: 0; 128 to 353207
Function: Specifies the u pper l imit o f the ATM connection conforming avera ge rat e on t he
transmitting side. The average rate equals the total number of cells transmitted, divided by the durat ion of t he connect ion. The de fault va lue, 0, indicates t hat the transmit SCR is off.
Using the sustainable cell rate (SCR), you can define the future cell flow of a VC in greater detail than by using only the peak cell rate.
The SCR maps directly to the minimum cell rate (MCR). The MCR defines the minimum amount of guaranteed bandwidth allowed for the default VC on the ATM line.
When setting the SCR, keep the following in mind:
• To be useful, the SCR must not exceed the PCR.
• If you know the average rate, set the SCR approximately 10 percent higher
than this va lue.
• VCs may fail to operate with SCR values lower than 128 cells/s.
• Entering 0 for the SCR turns o ff this function.
Instructions: After you determine the transmission rate of your ATM device, set the
sustainable cell rate within the speci fied range. En ter 0 to turn off this function.
